摘　　要：橡胶粉改性沥青路面因其良好的性能和显著的经济效益,近年来在公路工程中得到广泛应用,但碾压不充分、路面残留空隙率过大等问题一直未得到解决,本文就改性沥青混合料的碾压工艺及注意事项,从碾压温度、碾压厚度、压实程序和模式等4个方面提出了改进沥青路面碾压工艺的建议。Due to good performance and remarkable economic benefits,rubber powder modified asphalt pavement has been widely used in highway engineering in recent years,but some problems such as insufficient roller compaction and excessive void ratio have not been solved.This paper analyses the rolling process and matters needing attention of modified asphalt mixture,and puts forward some suggestions of improving the rolling process of asphalt pavement.
